carl ageeNorthwest Africa (NWA) 7034 is a new type of martian meteorite discovered in Morocco in 2011. NWA 7034 aka "Black Beauty", nicknamed for its dark shiny appearance, contains ten times more water than other martian meteorites. This combined with its oxidation state which is highest among martian meteorites, its anomalous oxygen isotope values, and its early Amazonian age, make it an extraordinarily valuable specimen for understanding surface processes, aqueous alteration, and atmosphere/lithosphere exchange reactions that existed on Mars ~2 billion years ago.

Dr Agee will show that Black Beauty appears to be the first martian meteorite to match the surface geochemistry of Mars, as seen by landers and orbiters, and as such, it has particular relevance to the current Mars Science Laboratory mission at Gale Crater.
